OGDL (Ordered Graph Data Language) is a structured
textual format for representing graphs of
information. Its grammar is very simple, allowing
for very compact parsers. It is a readable
substitute for XML in data applications (such as
configuration files).

skd is a tool for the simple distribution of SSH keys in a growing environment. It allow you to create hosts, group them, and link that group a group of users with keys to easily distribute all affected keys. skd generates a DSA or RSA keypair, which is saved to its database and used as the authentication source for skd itself. This keypair can (and should be) additionally be encrypted using a passphrase. This allows you to simply add a user with their key and press one button to grant (and revoke!) the user's access to all needed hosts.

The mctdhtools project aims to provide a set of routines for easily reading and manipulating the output of the Heidelberg MCTDH code. Its goal is to allow a new user to quickly get started with writing custom analysis programs, and to allow more experienced users to write small, clean, and testable analysis programs, something that seems incompatible with the Fortran-77 code of the Heidelberg MCTDH package.

PGObject::Simple::Role provides an interface to the PGObject service locator for Moo and Moose Perl classes. This service locator is intended to integrate Perl objects with PostgreSQL user-defined functions, and this uses the "simple" mapping approach. Between PGObject::Simple::Rrole and PGObject::Util::DBMethod, it is possible to write fully-declarative classes in which all calculation logic is handed off to database functions.

sftp4tc is a file system plugin for Total Commander that allows SFTP sessions to connect to your Unix/Linux servers. It supports Unicode file name translation, server-to-server copy, and all usual operations. Because it is based on PuTTY, you can use all your configured servers from PuTTY, and it also supports the Pageant private key agent.
